The screw Angle of twist drill mainly affects the size of cutting edge Angle, edge edge strength and chip removal performance, which is usually 25 32 Spiral grooves can be processed by milling, grinding, hot rolling or hot extrusion, and the front end of the drill bit forms a cutting part after grinding. The cutting Angle of the standard twist drill is 118, the bevel Angle of the cross edge is 4060, and the back Angle is 8 20. Due to structural reasons, the rake Angle is large at the outer edge and gradually decreases to the middle, and the transverse edge is negative rake Angle (up to about -55), which acts as extrusion when drilling. we are a professional manufacturer of power tool accessories, we are specilized in various cutting tools and tool set, drill bits, hole saw, cutting discs, etc. Our Twsit drill bits are exported to many countries all over the world.

We have about 19.000 micro drills, made of HSS an some of Carbon steel. They are from Swiss and German manufacturers. The drills are old, but still in their original unopened packing. They were stock from a specialised machining factory, that closed their doors in The Netherlands and moved production to China. Sales price of the whole lot, if you have to buy per 10 new pieces, would be â?¬240k. These drills are old and will not reach this value, when sold in the marker, and I understand the buyer of this lot also needs to make his profit. If you are interested, please make me an offer.
